Y VEHICLE TIRE.

Application filed March 7, 1925. Serial No. 13,746.

To all whom t may concern.:

Be it known that I, GEORGE HADRICH, a citizen of the United States, residing at Highland Park, in the county of l/Vayne and State of Michigan, have invented certain new and useful Improvements in Vehicle Tires, of which the following is a specification, reference being had therein to the accompanying drawings.

This invent-ion relates to vehicle tires and the primary object of my invention is to provide a novel rim for a solid rubber tire, or other yieldable tread member, which is adjustably supported and adapted to be cushioned by a compressible member within the tire rim.

Another object of this invention is to provide a strong and durable wheel rim having a detachable side member which permits of the tire being easily and quickly assembled relative to the rim.

A further object of my invention is to provide a tire possessing the resilient and cushioning characteristics of an ordinary pneumatic tire, but devoid of springs and such elements that deteriorate and cause tire troubles.

A still further object of my invention is to provide a vehicle tire that may be advantageously used on tractors, trucks, and other types of heavy-duty motor vehicles.

The above and other objects are obtained by a tire construction that will be hereinafter specifically described and then claimed, and reference will now be had to the. drawings wherein Figure 1 is a side elevation of a tire, partly broken away and partly in section.

Figure 2 is a longitudinal sectional View of a portion of the tire, taken on the line II-II, of Figure 5.

Figure 3 is a longitudinal sectional view of a portion of the tire, taken on the line Ill-III, of Figure 5.

Figure 4 is a longitudinal sectional view taken on the line 117-117, of Figure 5.

Figure 5 is an enlarged cross sectional view of a tire, and,

Figure 6 is a horizontal sectional view taken on the line VI-VL of Figure 5.

In the drawings, the reference numeral 1 l denotes a rim provided with inwardly projecting side flanges 2 and 3, and an inner outwardly projecting annular hollow wall 4. Opposite the inner wall 4, is an outwardly projecting annular web 5 and adapted to be attached to this web, by set screws 6, or other fastening means, is an outer hollow annular wall 7, adapted to cooperate with the inner wall 4 in forming a channel, into the outer portion of which extends the infelloe, or the outer ends of the spokes and.

suitably retained in engagement therewith.

The tire 8 is mounted in a channel member 14 and this channel member has side walls 15, providing annular grooves 16, into which extend annular ribs 17, carried by the confronting faces of the walls 4 and 7. The grooves 16 are of a greater width than the ribs 17, so that the channel member 14 may slide, with a limited action, between the walls 4 and 7, which brace and engage the side walls of the tire 8. The side walls 15 of the channel 'member 14 are provided with radially disposed slots 18, and extending into said slots are guide pins 19 carried by the walls 4 and 7, of the rim 1. The side walls 15 of the channel member 14 engage in the side walls of the tire 8, so that the side walls of the tire may be flush with t-he outer faces of the walls 15 for sliding engagement with the walls 4 and 7.

Disposed at intervals in the channel of the rim 1 are arcuate plates 2O and these plates and the channel member 14 have the confronting faces thereof provided with sets of bosses 21 for the tubular portions 22 of a continuous circumferentially disposed hollow cushioning member 23, said member having its tubular portions 22 connected by hollow webs 24. The cushioning member is preferably made of rubber and the plates 20 support said cushioning member in engagement with the channel member 14 by virtue of set screws 25 adjustable in bosses 26 of the rim 1. The set screws 25 may be held by lock nuts 27 and the outer ends of said screws may be enclosed by caps 28 mounted on the lock nuts 27 or the bosses 26.

The plates 20 are guided by pins 29 carried by therim 1 and extending into openings A-prrov'ided therefor in the plates 20. The cushioning member 23 may yhave ,11ecesses providing clearance `for vthe .ends of the guide pins 29.

By adjusting the screws 25, pressure may be brought to bear on the cushioning member 23 and from time Lto atime .tliefexpansive force of the cushioning member may be regulated.V

lThere Vmay Ebe vfour, or more,v of the set screws 6, Vand easy access -may be had .to these lset Iscrews thro-ugh openings 81 in the detachable wall 7, said -zopenings `being normally closed lby screw plugs 32.

a`'Thetire may 'be Vprovided with any-suitable tread and the rim and itsside walls 'may be of metal; th'e tire f8 is 'welil braced and protected. The :cushioning member is also enclosed and protected against stone fbruise. W'ith :this cushioning `member Epossess'ing greater :resiliency than *the rubber tire l'8, said cushioning lmember :can tbe readil-y mounted in the channel 'of the rim and other parts `'easily 'assembled relative thereto.

vfit is thought that the utility of my yehicle tire will lbe apparent without further description and whilein fthe Adrawing there is illustrated a preferred #embodiment of my "invention, 'it :is to' :be understood 4that the `ture.

gaging said channel member, and means carried Eby .said -rim for compressing said -cushioning imember.

'2. .A vehicle `,tire construction, as called for in claim l, wherein said cushioning member is made of rubber with hollow webs and hollow tubular portions.

A wehicle ltire Vconstruction comprising a channel rim, -a tire slidable in said rim, :a channel :member supporting .said tire, adjustable plates fin fsaid channel rim, and a compressible cushioning member between saidachannel member and said `pla-tes, :said oompressible cushioning member being made oli' 4rubber and formed Withwhollow `web and tubular portions.

in testimony whereof I .aiix vmy .signaenonen Mannion.
